Time evolution of e and Porb for 3 M⊙ + 3 M⊙ binaries over a grid of initial orbital periods and initial eccentricities. The colors represent the various stellar types encountered by each binary over its evolution. The binaries end in either stellar merger or as carbon–oxygen WD (COWD) binaries at ∼450 Myr.
